目的:探索多囊卵巢综合征(PCOS)患者血清中锌αn 2糖蛋白(ZAG)水平随代谢指标变化的规律，寻求PCOS患者代谢紊乱与ZAG之间的相关性，为PCOS患者代谢紊乱的诊治提供依据。n 方法:选取2017年1月至2018年6月广州中医药大学深圳医院(福田)就诊的汉族PCOS患者200例为试验组，根据体质量指数(BMI )分为试验A组100例(BMI≥25 kg/mn 2)和试验B组100例(BMI<25 kg/mn 2)；同时筛选在此期间来院体检的健康汉族女性100例为对照组。检测ZAG、空腹血糖(FPG)、空腹胰岛素(FINS)、甘油三酯(TG)、总胆固醇(TC) 、低密度脂蛋白(LDL)以及高密度脂蛋白(HDL)，比较三组间差异。试验A组在控制体质量后，复查以上指标，比较这些指标的前后差异。n 结果:试验A组中FPG、FINS、HOMA-IR、TC、TG、HDL、LDL、ZAG分别为(5.92±0.51)mmol/L、(19.94±3.15)mIU/L、(5.29±1.19)、(5.59±0.49)mmol/L、(2.03±0.35)mmol/L、(0.72±0.21)mmol/L、(3.05±0.43)mmol/L、(35.80±8.12)ng/mL，试验B组分别为(5.38±0.62)mmol/L、(15.67±4.59)mIU/L、(3.84±1.45)、(4.61±0.65)mmol/L、(1.49±0.35)mmol/L、(1.24±0.40)mmol/L、(2.61±0.40)mmol/L、(45.22±10.27)ng/mL，对照组分别为(4.77±0.53)mmol/L、(11.66±3.23)mIU/L、(2.52±0.95)、(4.59±0.53)mmol/L、(1.39±0.26)mmol/L、(1.40±0.31)mmol/L、(2.50±0.35)mmol/L、(59.15±8.90)ng/mL，试验A组与试验B组、试验A组与对照组、试验B组与对照组差异均有统计学意义(n F＝36.81、41.04、44.05、33.65、38.61、39.25、18.45、56.88，均n P<0.01)。试验A组在控制体质量后，FPG、FINS、HOMA-IR、TC、TG、HDL、LDL、ZAG分别为(5.27±0.54)mmol/L、(15.67±3.16)mIU/L、(3.72±1.06)、(4.98±0.45)mmol/L、(1.62±0.30)mmol/L、(1.03±0.25)mmol/L、(2.82±0.43)mmol/L、(43.59±8.20)ng/mL，试验A组在控制体质量前后相比差异均有统计学意义(n t＝15.26、15.67、17.70、11.04、17.61、－9.61、22.83、－13.79，均n P<0.01)。血清ZAG与HDL呈正相关(n r＝0.628，n P<0.01)，与BMI(n r＝－0.685，n P<0.01)、HOMA-IR(n r＝－0.729，n P<0.01)、TC(n r＝－0.579，n P<0.01)负相关。n 结论:PCOS患者的ZAG值降低，其中以肥胖组更低，并与HDL呈正相关，同时和BMI、HOMA-IR以及TC呈负相关，可见PCOS患者代谢情况可以通过ZAG得到相应的体现，对诊治PCOS患者代谢紊乱有一定的价值，为今后深入研究PCOS代谢紊乱提供了理论依据。“,”Objective:To explore the changes of serum zinc-2 glycoprotein (ZAG) levels in patients with polycystic ovary syndrome (PCOS) with metabolic indicators, and to seek the correlation between metabolic disorders and ZAG in patients with PCOS, so as to provide a basis for the diagnosis and treatment of metabolic disorders in patients with PCOS.Methods:A total of 200 Han PCOS patients admitted to Shenzhen Hospital of Guangzhou University of Traditional Chinese Medicine (Futian) from January 2017 to June 2018 were selected as the observation group, and divided into the group A (BMI ≥ 25kg/mn 2) and the group B (BMI <25kg/m n 2) according to body mass index(BMI). Meanwhile, 100 healthy Han women who came to the hospital for physical examination during this period were selected as the control group.ZAG, fasting blood glucose (FPG), fasting insulin (FINS), triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were measured, and the differences among the three groups were compared.After weight control, group A reviewed the above indicators and compared the differences of these indicators before and after weight control.n Results:In group A, the FPG, FINS, HOMA-IR, TC, TG, HDL, LDL and ZAG were (5.92±0.51)mmol/L, (19.94±3.15)mIU/L, (5.29±1.19), (5.59±0.49)mmol/L, (2.03±0.35)mmol/L, (0.72±0.21)mmol/L, (3.05±0.43)mmol/L, (35.80±8.12)ng/mL, respectively, which in group B were (5.38±0.62)mmol/L, (15.67±4.59)mIU/L, (3.84±1.45), (4.61±0.65)mmol/L, (1.49±0.35)mmol/L, (1.24±0.40)mmol/L, (2.61±0.40)mmol/L, (45.22±10.27)ng/mL, respectively, which in the control group were (4.77±0.53)mmol/L, (11.66±3.23)mIU/L, (2.52±0.95), (4.59±0.53)mmol/L, (1.39±0.26)mmol/L, (1.40±0.31)mmol/L, (2.50±0.35)mmol/L, (59.15±8.90)ng/mL, respectively, and the differences were statistically significant between group A and group B, between group A and control group, and between group B and control group(n F=36.81, 41.04, 44.05, 33.65, 38.61, 39.25, 18.45, 56.88, all n P<0.01). After weight control, the FPG, FINS, HOMA-IR, TC, TG, HDL, LDL and ZAG in group A were (5.27±0.54)mmol/L, (15.67±3.16)mIU/L, (3.72±1.06), (4.98±0.45)mmol/L, (1.62±0.30)mmol/L, (1.03±0.25)mmol/L, (2.82±0.43)mmol/L, (43.59±8.20)ng/mL, respectively, and the differences were statistically significant in group A before and after weight control (n t=15.26, 15.67, 17.70, 11.04, 17.61, -9.61, 22.83, -13.79, all n P<0.01). The serum ZAG was positively correlated with HDL (n r=0.628, n P<0.01), and negatively correlated with BMI (n r=-0.685, n P<0.01), HOMA-IR (n r=-0.729, n P<0.01), and TC (n r=-0.579, n P<0.01).n Conclusion:ZAG value is reducedin PCOS patients, with lower level in obesity group, and is positively correlated with HDL, negatively correlated with BMI, HOMA-IR, TC.The metabolism in patients with PCOS can be reflected by ZAG, which has a certain value in diagnosis and treatment of PCOS patients with metabolic disorder, and provides theory basis for further study of the metabolic disorder of PCOS.
